Real-Time Digital Filtering Reduces Noise and Lets You Find Your Hidden Waveforms
The real-time digital filtering lets you easily apply a low pass
filter while capturing data, so that waveforms hidden in noise
can be clearly displayed. Filters can be set separately on each
channel. In combination with an analog filter, cutoff frequencies
ranging from 20 MHz to 10 kHz can be set. Additionally using
the real-time digital filtering and the high-resolution mode,
vertical resolution is increased to as many as 13 bits, and
signals can be reproduced even more
accurately on the screen. This helps to
evaluate ECU signals containing ignition
noise and inverter output superimposed
with high-speed switching noise.

Super-Long Memory & Roll Mode
Web Server Functions
Super-long memory enables you to capture high-speed
phenomena for the desired period of time, while maintaining fast sampling speeds required for reliable measurements. The DL1620 can acquire up to 8 MW of data on
each channel. Time/div can be set to as slow as 800 s/div,
allowing you to acquire data for over two hours. You can
observe waveforms in roll mode, while checking surge
pulses and discontinuities in zoomed waveforms. This is
helpful for observation of signals from power supplies.
Results from waveform parameter calculations such as
peak-to-peak values, frequency, and FFT calculations can
be displayed while observing the waveform in roll mode.
The DL1620 enables you to observe signals as long as
those normally observed using recorders.
Connect the DL1620 to
your PC using an Ethernet
connection. This allows for
easy remote operations
using Internet Explorer.
FTP
You can easily copy and paste
files to and from a PC and the
instrument’s flash memory or
other storage media.
Data Capture
Using Internet Explorer, you can
periodically or manually download
screen images to a PC for remote
waveform monitoring. You can
also download waveform data,
start or stop a measurement, or
setup a split display all from a PC.
Measurement Trend
This function downloads values of
waveform parameters periodically,
launches MS Excel and graphs
the parameters on a spreadsheet
values. This enables you to
check the parameter trends at a
glance.
